The key is have found is leave the sink running with the sink attachment in the siphon position, and most important make sure the valve is open at the gravel vac end then just roll it up and walk it back to the sink,.

Ha ha .. how funny ... I just purchased an Aqueon water changer yesterday. After nearly three years of PWC's via buckets ... relax .. I actually enjoyed it, let me think about things, it was just taking too much time to change 15gallons ... let alone 25 - 30gallons.

Funny because I had the same issue with left over water ... there is a you tube video that shows the hose rolled up by the demonstrator at the end of the PWC.

Just wanted to follow up and say that walking it back with the valve open and the water on at the sink did the trick nicely. The Python makes water changes so easy it really is amazing. I would have gotten back into the hobby sooner if I had realized what a difference these things make! Thanks again for all the help.

I leave water in mine. I don't hook to the faucet until I fill the tank back up, so leaving water in the tube creates instant suction next time I need to do a water change. I just store it in a box under my tank between changes.

Are you talking about a python or just a normal gravel vac? Either way, leaving stagnant water in the line is not a good idea. The water pressure from your sink creates the siphon, no need to save it.

An Aqueon Water changer -like a python. And I don't hook it to the sink to create a siphon. I drain out the door and only hook it to the sink when I refill the tank. The stagnant water doesn't go anywhere but out the door, and as it drains it pulls tank water out with it, creating my siphon.
